struct.node.acc.local

Syntax

m := struct.node.acc.local(sn<,i>)

Get the generalized acceleration (expressed in the node-local system) of the structure node.

Returns:

m - matrix of acceleration with all degrees-of-freedom if the argument i is not assigned, or acceleration at the ith degree-of-freedom if the argument i is assigned.

Arguments:

sn - pointer to a structure node

i - degree-of-freedom, i ∈ {1, 2, … , 6} or {1, 2, 3} in 2D. The default is 1.
